HENRY ANDREW FENSKY, OF LADYSMITHfWISCONSINQ PULP-FEED REGULATOR.

. Specification of Letters Patent. Patented Nov. 15, 1921.

Application filed August 14, 1920. Serial No. 403,534.

To all whom it may concern Be it known that I, HEN Y A. FENsKY, a citizen of the United States, residing at Ladysmith, in the county or" Rusk and State of Wisconsin, have invented new and useful Improvements in Pulp-Feed Regulators, 0t which the following is a speclfication.

This invention relates to weighlng means for pulp machines, the principal object of the invention being to provide means for dellvering a stream of pulp oi uniform weight to the mixing box from the stuff box, the

weight of the stream being kept uniform by the automatic action of said means.

Another object of the invention is toprovide means whereby the stream of pulp may be kept at any desired weight.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views and in which Figure 1 is a side view of the invention.

Fig. 2 is a front view. I

Fig. 3 is a horizontal section on line 3 3 of Fig. 1. r

Fig. 1 is a detail view of the hopper.

Flg. 5 1s a view of the gage or spout men1- ber.

Fig. 6 is a view of the dripping pan or spout.

In these views 1 indicates the stuff box to which the pulp is supplied by the inlet pipe 2 and 8 indicates the outlet pipe or overflow. 4: indicates a valve for controlling the outlet pipe 3. A port 5 is formed in the upper part of the box 1 and a reinforcing strip 6 is placed on the front of the box and this strip has guideways therein on each side of the port. The gage or spout member 7 is slidably mounted in said guideway and said gage has an opening 8 in its upper part for registering with the port when the gage is in its lower position. A spout 9 is carried I by the gage for receiving the material passing through the opening 8. A stem 10 is formed on the upper end of the gage having an eye 11 in its upper end and a weight ,i'e-st 12 is carried by said stem, A. frame 13 is secured to the strip 6 and bearings 14 are formed in theouter parts of said tranietod receive the U-shaped member 15. Uprights 16 are carried by the frame 13 and these uprights support a pulley 17. A cable 18 has one end connected with the eye 11 and its other end connected with the cross piece of the U-shaped member 15. a

A hopper 19 is carried by the ends of the ill-shaped member 15 and this hopper receives the lower end of spout 9 so that the material flowing through said spout will be received in the hopper. This hopper is of substantially the shape of an inverted cone with an outlet spout 19 at its lower end from which the pulp will drop into the mixing box 2-0 or to any other place where wanted.

The hopper is provided with a partition 21 whlch leaves a space between its lower end and the adjacent part of the hopper so that the material in the hopper can slowly pass through this space and also over the top of will flow into box 1 through the pipe 2 and out again through pipe 3. l/Vhen the valve 4: is closed, however, the stock will rise in the box 1 and when it reaches the port 5 it Will pass through the same and through the opening in the gage and drop from the spout 9 into the hopper and from the hopper drop into the mixing box. A weight is placed on the rest 12 before the valve is closed and this weight will then force the gage to the bot tom of the guideways and open the port 5 to its full extent. This downward movement of the gage will raise the hopper 19. The weight of thematerial dropping into hopper will lower the same and thus raise the gage and partly close the port, the extent oi movement of the parts corresponding to the size of the weight placed on the rest. For instance, if the stock is being delivered to the box 1 at the rate of pounds a minute and a 40 pound wei ht has been placed on the rest, the stream or pulp dripping into the hopper at first will be the same as has been delivered to the box. That is, at the rate of 80 pounds a minute This weight will force the hopper downwardly to raise the gage until thestream dropped into the hopper'will' be reduced to 40 pounds, In other words, the weight of the stream passing through the reduced port will be the same as that of theweight on rest 12 so that by placing different sizes of weights. upon said rest the weight of the stream of pulp passing into mixing'tanlr 4 canbe regulated and thisrweight will be keptuniformauto- :maticallyby the device. [Asis well under- :stood, the different kinds of wood from which'the pulp is made has difierent weights and the'pulp will vary in Weight according to the kind used. By the use of my machine,

- f however," the flow will be so regulated that j a; stream of the same weight will be dis- "charged into the mixing box; The paper made by the pulp handled by my machine will be of uniform weight as the pulp is weighed before the paper is made.

The adjustment of the gate in the hopper will also act to regulate the weight of the 7 tion that the advantages and novel features pulp. The long spout will act to prevent splashing of the pulp in the hopper. 3

It is thought from the foregoing descripof my invention will bereadily'apparent.

'I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts,-provided that such changesfall within thescope of the appended claims.

"What I claim is 1. In combination with a stuff box and mixing box of a paper pulp apparatus, a

- gage plate for controlling the outlet port of the stuff box, a spouton said gage plate, a

hopper vfor receiving the pulp in said spout and directing it into the mixing box, a slid- V able frame connected with the hopper, a pul-,

. gage plate. r

ley, a cable connecting the slidable frame with the gage plate and passing over said pulley and'a Weight rest, connected with the 2. A device of the class described comprising a tank, having an outlet porttherein, a

gage plate controlling said port, a spout on the gage plate, a hopper for receiving the material from the spout and deliverlng it to the point'o'f use, a slidable frame supporting *saidhopper, a pulley, a cable passing over said pulley and having one end connected with the gage plate and its other to the slida-ble frame and a weight rest connected with said gage plate.

3. An apparatus of the class described 7 comprising a tank having an outlet port therein, a guldeway formed on each side of connected with the gage plate and its other to said frame and a weight rest connected with said gage'plate.

4. An apparatus of the class described comprising a tank having an outlet port, therein, a gage plate for controlling said 'outlet port, a spout carried by said gage plate, a hopper into'which the spout pro- 7 jects, flexible means for connecting the gage plate with the hopper, a pulley over which said flexible means pass, a weight connected with said gage plate, said hopper having an outlet port therein and a gate for controllingsaid port; a r l v 1 In testlmony whereof I affix my signature.
